MIPS: Loongson: Oprofile: add a new do_perfcnt_IRQ()
On FuLoong-2F IP6 is shared by the performance counter overflow interrupt and the Bonito northbridge interrupt. To reduce overhead only call do_IRQ() when oprofile is enabled to reduce overhead. This patch adds an inline function do_perfcnt_IRQ() to hide the #if's , which can be shared by the other Loongson machines, i.e. gdium.
